Abstract
The utility model relates to a atmospheric hot water unit, provided with both spray and indirect heat transfer, which comprises a burner, a combustion chamber, a insulating layer, a spray plate, a heat transfer, a water-jacket interlayer, a smoke vent, a water inlet, a water outlet and a water storage tank. A plurality of horizontal or vertical mental heat transfers, none of which is communicated with the others, are staggeringly arranged between the combustion chamber and the smoke vent. The horizontal mental heat transfer is a flue gas channel and the vertical mental heat transfer is a water channel. Water is sprayed on the topside of the vertical passageway via the spray plate for heat absorption along the vertical passageway, and then free drops for speedup of the water flow, aimed at a high heat transfer coefficient. The unit has the advantages of high efficiency, small bulk and light weight.
Description
The utility model relates to a kind of, and the atmospheric hot-water unit that adopts spray to engage with indirect heat transfer is mainly used on central air-conditioning heat supply, hot water system and the hot water supply system.
At present, the structure of atmospheric hot-water unit is based on the fire-tube type structure, and the high temperature that produces after the fuel combustion with the water outside the heat transferred fire tube tube wall, improves the temperature of water through the tube wall of fire tube.Heat of high temperature is that the heat transfer of a complexity passes journey through the process of tube wall transmission feedwater, is subjected to the influence of pipe thickness, pipe wall material, flue gas flow rate, water velocity.What hot water unit heat transfer coefficient was had the greatest impact is the flow velocity of water, and the hot water unit makes the flow velocity of water in unit very low owing to be subjected to the restriction of set structure, has caused the unit heat transfer coefficient little.Therefore, the volume of unit is big, and efficient is low, the cost height.
The purpose of this utility model provides a kind of, adopts with the water spray on the heat-transfer pipe tube wall the novel atmospheric hot-water unit that the spray of augmentation of heat transfer coefficient engages with indirect heat transfer.
The purpose of this utility model is achieved in that fuel oil or combustion gas through burner, after doing to burn fully in the combustion chamber of unit, forms the flue gas of high temperature.After high-temperature flue gas enters the heat exchanger that is contained between combustion chamber and the exhaust opening, carry out heat exchange with vertical shower water, with heat transferred water, flue-gas temperature reduces the back and is discharged by exhaust opening.Heat exchanger is made by metal material, and staggered anyhow not connected heat exchanger laterally is an exhaust gases passes, vertically is the shower water passage.Shower water is by the vertical passageway top of the uniform spray of shower plate at heat exchanger, water flows freely the raising flow velocity downwards along the vertical passageway, absorb the heat of high-temperature flue gas in the transverse pipe, falls into water storage tank after the hot water heat absorption heats up, hot water is sent by the delivery port of water storage tank, uses for the user.User's backwater enters unit by water return outlet, and along peripheral water jacket samdwich, the mouth spray that enters shower plate is with water, and evenly spray is on the top, vertical passageway of heat exchanger.In order to reduce the peripheral thermal losses of unit, adopt insulation material to do insulation and handle.
Owing to adopted such scheme, the flow velocity of water in the unit is improved, the corresponding heat transfer coefficient that improves unit reduces the volume of unit, efficient improves.
Below in conjunction with drawings and Examples utility model is further specified.
Accompanying drawing is a sectional structural map of the present utility model.
1. burners, 2. combustion chambers, 3. heat-insulation layers, 4. shower plates, 5. heat exchangers, 6. water jacket samdwich, 7. exhaust openings, 8. water return outlets, 9. delivery ports, 10. water storage tanks among the figure
In the drawings, burner 1, with fuel oil or combustion gas with light after air mixes, spray into combustion chamber 2 downwards, burning produces high-temperature flue gas, and high-temperature flue gas is by the heat exchanger between combustion chamber and the exhaust opening 5, laterally enter heat exchanger, carry out heat exchange with vertical shower water, the flue gas that is cooled is discharged outside the unit by exhaust opening 7.User's backwater is by water return outlet 8, enter behind the unit along peripheral water jacket samdwich 6, enter shower plate 4, mouth spray is sprayed on water the top, vertical passageway of heat exchanger uniformly, water flows freely downwards along the vertical passageway again, absorbs the heat of high-temperature flue gas in the transverse pipe, falls in the water storage tank 10 after the hot water heat absorption heats up, by delivery port 9, send for the user and use.In order to reduce the peripheral thermal losses of unit, unit adopts heat-insulation layer 3, does insulation and handles.
Claims (6)
